This is the final project for Coursera course I’ve completed in December 2020.
The process is summarized as follows: a network of points on a plane formed the first squares. The grids of the upper squares were formed by the tokenization of a random number and several “If conditions”. Eventually, the squares were swiped together.
I put the code here to find out exactly what I did.
import rhinoscriptsyntax as rs
import random as rnd
def PointMatrix(IMAX,JMAX,KMAX):
#set up empty list
ptList = []
ptDict = {}
#loop to generate point values as a product of the loop counter
#save values in list
for i in range(IMAX):
for j in range(JMAX):
for k in range(KMAX):
#define x,y,z in terms of i,j,k
x = i #+ (i*i)#* 5 #+ (rnd.random()*3)#
y = j #* 3 #+ (rnd.random()*5)
z = k #+ (k*k)#* 5 #+ (rnd.random()*3)#
#save point values in dictionary
point = (x,y,z)
ptDict[(i,j,k)] = point
#print out dictionary key:value pairs
#print (i,j,k), ':', point
#render point in rhinospace
#rs.AddPoint(point)
#main itteration
for i in range(IMAX):
for j in range(JMAX):
for k in range(KMAX):
if i > 0 and j > 0 and k > 0:
